being rcarriedby suitable Aoasters12"topermit vfare provided with ahorizontal frame portion K staggered jlrelation ,with .those of 1 theopposite portion'29.

thefrarne to be moved from one position toA another. y

:'Carried by one side ,of the frame 12 is .a .pair .of upright members1,3, the upper endso which 14. `Said -frarne portion is carried bybrackets A 1 5 .on the.upp,er-ends of the members r13, and

comprises .side members -l6 bolted to ther-bracket lbybolts 17. Theforwardends oi the meme `bers 16` Aare connected bya Lcross bar 18.

The side members 16 are each provided with -a longitudinal slot 179,said slots being designed to support -a square shaft 20 having roundedportions 2l ataeach end, which project through the slot .19..-Retativelymountedin Eheiforward end of the member 1'6 isa secondsquareshaft 22. Each of saidsnafts .20am f22 hase Series of what vLshall termf;ple atingfingers 23 slidably mounted longitudinallypf the shafts. n

supported va1ternately between .the lingers 23.75 are a. number.ofsprings A24 ifor hold-ing the fingers 'yieldablyl in .Separatedrelationr `with each other. The :fingers 2 3 .of @the shaft 120,: are.supported normally in staggeredrelation with .those ofv the shaftg22int-he manner clearly illustrated in Figures -3 and .4.. y y

' A sleeve 25 is supportedbetween the adjacent frame memberl vand theirst fingers 2 3 of the shaft Ztl-.to .properly .space rthe saidiingersin 85 shaft. The `other end of the sha-ft 21 is provided l-with atruck arm 2.6 jhaving a roller l27 designed to v:travel on a .trackr 28securedfto the inner lface .of .the .adjacent frame `lmember. 16`asillustratedxin Figure V5. The y.forward end vof the itrack281terminates iin a downwardly inclined A tongue I3,0.has .oneendApivoted fat the point 31 to :the .frame ,member 16. The top of thetongue l30 isin .line with the vtop or" the track 28. .One vend .of vtheshait 22 is provided f-with anarm .32 which'extends rearwardly and isprof' vided lWith .a slot .33 for vreceiving the roller 27. Thev bottomof the slot v33 is in :line -withathe top edge ofthe tongue 30. Themember'32 also .100 has an upwardly vextending portion 3.4' designed to.engage .a .latch member :35 .to support the. free endof :the :member 23against downward move.- ment. IA .spring `36 is provided for retaining.the

` latch Vyieldably-against a stop vpin 37 and in the 105 Cil 39, andalso with spring members adjacent to said pins. The parts are soarranged that if the bar 20 is at its outer limit of movement in theslots 19, then the upper end of the bag 41 may be applied tov a numberof the pins 39 and beneath the spring members 40, in such manner as tohold the bag in an open position, illustrated in Figure 3.

The roller 27 prevents the inner ends of the fingers 23 from turningdownwardly due to the weight of the bag, while the latch 37 supports theinner end of the fingers Von the shaft 22 against downward movement.

By this arrangement it will be seen that diiferent size bags may bethreaded von the fingers 23. The bars 2l and 22 are of such length inordinary practice as to take either small or large The maximum size bagis illustrated in Figure 3, in which case one or more free fingers areprovided at the ends of one or both of said shafts 2l and 22, the freefingers being indicated by the numeral 42.

The bottom of the bag is supported on an upwardly and forwardly inclinedvplatform 43, one end of` which is pvotally mounted on a transverselyarranged shaft 44 carried by the uprights 13. The said shaft 44 iscarried in suitablebrackets 45 adjustably mounted on the uprights 13 bysuitable set screws 46. Means is thus provided for accommodating bags ofdifferent lengths.

A spring 47 is vprovided for supporting the free end of the platform 43in its elevated inclined position. The rear end of the platform has anupwardly and rearwardly extending lever 48, by means of which the freeend of the plat-- form 43 may be oscillated up and down to cause thelower end of the bag to be elevated and lowered and the material within'the bag to be packed.

The platform 43 also provides means whereby the bag may be quicklydelivered from the holder by simply pushing the upper end of the lever Y48 forwardly against the tension of the 4spring 47,

permitting the platform to assume a downwardly inclined position. Y Thistakes place, however, after the sewing operation, hereinafter described,has been accomplished.

For moving the bar 20 toward the bar 22 to close the open end of thebag, I have provided in the frame member 10 a rock shaft 49, each endof-whichis provided withY an upwardly extending arm 50, the upper endsof the arms 50 having slots 51 for receiving the rounded portions 21ofthe shaft 20. Said arms 50 are supported outside of the frame members16. lOne ofthe arms' 50 has an upwardlyy extending portion 52 designedto carry a latch 53. Secured to one of the arms 50 is a lever 54extending forwardly and having a pedal 55. The rear end of the lever 54f extends rearwardly from the arm 50 and is designed to engage a springactuated latch 55a also pivotally mounted to the frame 10, said latchhaving a rearwardly extendingr portion 56 designed to be engaged by theoperators foot .for

` releasing the latch from the lever 54.

By this arrangement it will be seen that if the operators foot is placedon the pedal 55 andthe pedal lowered, then the upper ends of the arms 50willrbe moved forwardly, carrying with them the bar 21 together with therear edge ofthe open end of the bag. f

The arms 50 have a rearwardly extending loop portion 57 designed toengage the lowerend of the bag as the arm 50 ismoved forwardly, and tomove it forwardly along the upper surface of the inclined platform 43,causing the bag to be elevated to compensate for the shortening of thesides of the bag as they are moved inwardly over the upper end of thematerial therein.

Pivotally mounted on each side member of the frame 10, to swinglaterally is an arm 58. lThe upper end of each of the arms 58 isprovided with a short plate 59. Said plates 59 aredesigned to engage theouter ends of the sleeve portions of the outer fingers 23 when the bar20 has been moved toward the bar 22 to such position that the inner endsof the ngers of the bar 20 are substantially in alinement with the innerends of the fingers of the bar 22, or at a time when the upper edges ofthe bag assume a closed position, as illustrated in Figure 7.

Each of the arms 53 is provided with a Acam 60 designed to be engaged bya corresponding one of the arms 50 as it is moved forwardly in suchmanner that the arms 50 assume the position where the top of the bag isclosed, as shown in Figure 7. Said arms 50 will then engage the cams,causing the upper ends of the levers 58 to be moved-inwardly toward eachother upon fur'- ther forward movement of the arms 50, which will causethe'iingers 23 to be moved together at the same time the fingers oftheshaft 21 pass between the ngers of the shaft22, and thus cause the upperand adjacent edges .of the closed bag to be pleated in the mannershownin Figure j 4, at which time the latch 53 willengage the upper end ofthe member` 38, 'as-shown by dotted lines in Figure 5.

The rear end of thelever 54 will at this time be engaged by the upperend of the latch 55a to lock the bars 20 and 22 in said closed position.'As the bar 20 moves forwardly, the roller 2'7 travels on the uppersurface of the track 28 over the upper surface of the tongue30 andfintothegroove 33 ofthe' member32. x j,

It will beseen by referenceto Figures 1 and 6 that each of the fingersl23 is provided with a slot `61, the inner ends of the slots beingenlarged, while their outer'ends are somewhat-contracted.

It will furtherY be seen thatwhen thesaidbars are at their closedposition, asshow-nby dotted lines in Figure 6, the slots ofthe two setsof 1ingers are in alinement in such'a mannerKV that a needlemaybe-passed tiansverselyY through `all of said slots 61, and throughthe pleats of the upper end of the bag. A needle `62 is provided, havingan eye 63 near its pointed end for receiving a hook 64-of avsmall wire65, said wire being supported adjacentto one side of the' needle as theneedle is inserted through the pleatsin such a manner that the wire iscarried through the pleats. TheV free end of thewire is then bent toVform a hook to prevent the Vwire Afrom being moved from the pleatsaftergthe needle is removed. l p

The needle-is removed by simply supporting the free endof the wire inone hand; and pulling the needlerearwardlytoshove thehook 54 Yto theforward end of the `slot 63, after which the kwire may; be rotatedthrough an vlnglef ofV about 45, permitting ythe needlegto beremoved.

The vhoek portion 64, Win11 man retai one of the end pleats oftheyclosed -end,while the `newly formed hook on the free end of thewirevwill retain the other end pleat. .-fThebag is -then sewed inthemanner illustrated in Figure9.

, The operator k then places his foot on thememberr56, causingVtherlatch 55ato disengage ,the lever54. IA-spring 66 will then causevthe levers ii'to be moved rearwardly.. .As soon .asrthe member 52movesrearwardly, the-hook. SSV-willpmove the upper end :of the. member38 rearwardly and release the member 34 at Ythe time fthe-operatormoves. the free end ofthe member 48 forwardly, tilting the platform l.i3downwardly, whichtwill .permit the weightv of the .bag to loecarriedY'by the fingers 23 and the arm 32, inasmuch :asfthe roller 27 at thistime rests r-in said arm.`

` Fur-ther rearward movement togetherwiththe weight of the .bag willpermit the, free=ends .of the'arms `.26 and 32 to movedownwardlyf'andthe' shafts 20 and 22 to be rotated with the fingers 23in 'the position illustrated in Figure. 6, f at which time the bag willVbe disengaged from the .ends of the pins 39. Thex-rollerz27I willfmoverearwardly at the time thefree end of themember 32 is'being moveddownwardly, causing the said roller to disengage the 'slot 33-:andkto'vpass beneath the-pivot 3.1: of the-tongueY 3.0,.and upon furtherrearward VTVmovementto 'engage `thefinclined portion 29 in such mannerVthaty further rearward lmovement of the arm 52 will lcause the roller27V to ascend the inclined portion and elevate the free end of thetongue .30,"and to finally rest on the tracky 28,'causing the shaft 20'SGI to be returned .to its normal position. 1 f

A spring''? is provided for returning the shaft 22 toits normalposition. A stop-68 is provided for limitingthe rearward movement of themember 34 against the action of the spring 67.

Referring to Figure 7 it will be noted that as the upper edge of the bagis moved'to a closed position, then the side members69 of the bag willbe bulged outwardly from the outer pins 39. These outwardly extendingportions 69 will be pleated in the same manner as that portion on thesupporting pins.

I'have found by actual practice that unless an inclined platform, suchas 43, is provided,

then the upper folded edges of the side members 69 would draw downwardlyas the side members of the sack are moved together, but by providing theinclined platform, and means for moving the lower end of the bagforwardly and upwai-diy, then the upper edges of these side members areelevated sufciently to permit the entire upper edge of the folded bag toassume a substantially straight line when in the position shown j inFigure '7,

'i for sewing purposes, and in connectionl therewith improved means'for/sewing the same, the

bag holder being so arranged that the bag-may be placed ink operativeposition for lling,l after which it may be sewed and the entiremechanism run on a scale for weighing the contents of the bag, afterwhich it may-be transferred to any desired position, so that a singleplacing kof the bag in the holder accomplishes the filling, sewing,weighing and transferring, thereby eliminating a number of unnecessaryoperations.l
